Question 11
The link-state algorithm has the following properties:
it requires the source node to know the costs between every pair of adjacent nodes in the graph
after the kth iteration, the least-cost paths are known to k nodes
it determines the shortest path from the source node to all other nodes
all of the above
Question 12
In routing among ASs, which of the following issues dominants:
current congestion levels in the ASs
policy
number of ASs traversed
geographical distance between ASs
Question 13
Suppose an application generates chunks of 60 bytes of data every second, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will contain application data.
80%
20%
40%
60%
Question 14
Consider sending a 1300 byte datagram into a link that has an MTU of 500 bytes.
Three fragments are created with offsets 0, 480 and 96

15、runs directly on top of IP
16、all of the above
17、
18、
19、应该是6个子网，因为全0和全1的不可用，选项是那样的话他是按2的3次方吧，那就选 8 subnets, 8,190 hosts each
20、192.168.19.31 255.255.255.248
我也就只能帮这么多，知识基础不太够！
